THE introduction of leaf-mould as a compost for Orchids would seem to 
be an event of considerable importance, to judge from the account given at 
page 250 of your last issue, and if all that is claimed for the new compost 
proves true, I can quite understand the remark that Orchid culture will be 
practically revolutionized. Perhaps one can hardly call it ‘‘ new,” for it 
has been in use now for several years, and has been frequently recommended, 
though a good many growers have hesitated to adopt it, or only tried a few 
common things in it by way of experiment. A few growers, however, have 
used it on a larger scale, and I have several times seen plants either potted 
entirely or partly in it, which seemed as healthy and vigorous as could 
possibly be wished, and it has been remarked that there are now many 
thousands of Orchids in the country thriving splendidly in Belgian leaf- 
mould (terre bruyére). May they continue to thriveso! It will at all events 
be interesting to ‘ watch what developments follow when the more general 
use of leaf-mould for Orchids has been widely advocated.” 
podium fibre was strongly advocated as a 
potting material for Orchids, and | believe it is still much used in scme 
localities, though it has not been generally adopted as a substitute for peat, 
as some sanguine people prophesied, but whether this arises from any
